Vlastimil Babka 4b90ff885c x86/init: fix build with CONFIG_SWAP=n
commit 792adb90fa724ce07c0171cbc96b9215af4b1045 upstream.

The introduction of generic_max_swapfile_size and arch-specific versions has
broken linking on x86 with CONFIG_SWAP=n due to undefined reference to
'generic_max_swapfile_size'. Fix it by compiling the x86-specific
max_swapfile_size() only with CONFIG_SWAP=y.
